High-sensitivity deep shortwave infrared organic photodetectors enabled by selenium-integrated quinoidal molecular semiconductor

Developing organic photodetectors (OPDs) that can detect in deep shortwave infrared (deep-SWIR) region (1.2–1.6 μm) is technologically important. Yet, the performance of the state-of-the-art deep-SWIR OPDs remains substantially limited. Herein, we report a selenium-integrated qui...

Existence thresholds and limit profiles of ground states for lower critical Choquard equations with general nonlinearities

In this paper, we study the existence, non-existence and asymptotic behavior of positive ground states for the nonlinear Choquard equation: (0.1) − Δ ⁢ 𝑢 + 𝜀 ⁢ 𝑢 = ( 𝐼 𝛼 ⁎ 𝐹 ⁡ ( 𝑢 ) ) ⁢ 𝐹 ′ ⁡ ( 𝑢 ) , 𝑢 ∈ 𝐻 1 ⁡ ( ℝ 𝑁 ) , where 𝐹 ⁡ ( 𝑢 ) = | 𝑢 | 𝑁 + 𝛼 𝑁 + 𝐺 ⁡ ( 𝑢 ) with 𝐺 ⁡ ( 𝑢 ) =...

Volcano-Type Pore-Size Dependence of HMF Adsorption in Aluminum-Based Metal–Organic Frameworks: A Transport–Affinity Tradeoff for Sugar Purification

Furfural derivatives like 5-hydroxymethylfurfural (HMF) are potent fermentation inhibitors whose selective removal remains a bottleneck in biorefining due to limited pore-level mechanistic understanding. Here, we deploy five metal-organic frameworks with graded pore apertures to...

Experimental study and numerical simulation of shell-side heat transfer and flow characteristics of a novel continuous helical baffled heat exchanger without a central tube

This study develops and evaluates a continuous helical baffle heat exchanger without a central tube to address two limitations of existing shell-side designs: leakage between discontinuous helical baffles and the occupation of shell-side core space by the central support tube in...

Research on Flexural Performance of Truss-Reinforced Composite Slabs with a Single Rectangular Rib

Truss-reinforced concrete composite slabs (TRCs) are extensively applied in prefabricated construction, but the limited stiffness of precast base plates may lead to excessive deformation and cracking during construction. This study investigates the truss-reinforced concrete compo...

SCS-TCWave: an event-based hindcast dataset of typhoon waves and reconstructed wind fields for the South China Sea (1979–2025)

Abstract. Extreme-wave estimates for the South China Sea (SCS) depend on the peak sea states of tropical cyclones, yet reanalysis winds smooth the storm core and no openly archived, event-resolved typhoon wave record exists for the basin. We present SCS-TCWave, an event-based hin...

One-Pot Ketone Functionalization of EPDM toward Recyclable and Creep-Resistant Elastomers Cross-Linked with Biobased Amines

Abstract Introducing dynamic covalent networks into conventional ethylene-propylene-diene monomer (EPDM) rubber offers a promising strategy for developing thermally reprocessable elastomers; however, it requires the introduction of reactive functionalities onto the chemically ine...

TLD-YOLO: A Lightweight Detector with Cross-Scale Adaptive Fusion and Dual Attention for Tiny Litchi Detection and Counting in Unstructured Orchards

Accurate detection and counting of tiny litchi fruits in natural orchards are fundamental for approximate yield estimation and precision harvesting; however, small-target signals are easily lost during downsampling, while dense clusters, occlusion, and complex backgrounds further...

Thermal Behavior of a Large-Span Continuous-Welded Stainless Steel Roof System

The structure of the large-span metal roof system is complex, and the thermal effect at the key nodes under the thermal load of the operation is significant, leading to fatigue failure risk of load-bearing members and structural safety hazards. Existing studies on metal roof ther...

Digital performance accountability and legal governance in China: effectiveness and influencing factors

While previous studies have documented how the Chinese state deploys law and digital technologies to enhance social control, relatively little is known about whether local officials are more tightly monitored and regulated with the rise of law-based rule and digital governance. B...
